Second Hand BMW i3 Central Locking Motor

The BMW i3 does not use conventional central locking motors in the way that traditional petrol or diesel cars do. The i3 uses an electromechanical locking system integrated into each door latch assembly, so there is no separate, standalone central locking motor unit to source. If your door is not locking or unlocking correctly, the part you most likely need is the door latch mechanism itself, sometimes listed as a door lock actuator or door latch assembly — speak to a breaker and describe the fault so they can identify the correct component for your door and registration.

On the i3, locking faults are almost always traced to the door latch actuator, which is the combined latch and motor unit built into the door, rather than a separate central locking motor. You should search for 'BMW i3 door latch actuator' or 'BMW i3 door lock mechanism' and specify which door is affected (NS front, OS rear, etc.) as these can vary by position. Contact a breaker with your registration and the door location so they can pull the correct part from a matching vehicle.

The BMW i3 was produced from 2013 with a mid-life refresh arriving in 2017, and the facelifted models introduced some interior and minor body changes that could affect door latch fitment. The latch actuator design may differ between the pre-2017 and post-2017 cars, so crossing that boundary is something you should confirm with the breaker against your exact registration before buying. Never assume a pre-facelift part will drop straight into a post-facelift car without checking.

The door latch actuator is part of the door structure and is not affected by whether your i3 has the range-extender petrol engine or is purely battery electric — the doors are the same across both variants. When contacting a breaker, your registration number is the most reliable way to confirm the correct part, but you do not need to specifically seek out a Rex or non-Rex donor vehicle for this component. Focus instead on matching the year and which door you need.

Trim level does not affect the door latch actuator on the i3 — the locking mechanism is the same regardless of whether the car is a base model or a higher-spec Suite or Lodge trim. You may find that interior door furniture looks slightly different between trims, but the latch unit itself behind the panel is interchangeable across trim levels for the same generation. Always confirm with the breaker using your registration to be certain.

Findapart connects you with UK vehicle dismantlers (breakers) who can source used i3 door latch actuators from salvage vehicles, which is usually far cheaper than a new BMW main dealer part. When requesting a quote, give your full registration, specify which door is faulty (for example NS rear or OS front), and describe the fault so the breaker can confirm the right part. Used parts from a reputable breaker are a cost-effective option, though you should ask about any short warranty or returns policy before purchasing.
